PIOKING-MOTION FOR VERTICAL LOOlVIS.

To all whom it may concern:

Be it known that I, ROBERT ABELL, a subject of the King of Great Britainand Ireland, residing at Elm Tree House, Uttoxeter, New Road, in thecounty borough of Derby, England, have invented new and use fulImprovements in the Picking-Motion of Vertical Looms, of which thefollowing is a specification.

The object of my invention is to effect certain improvements in thepicking motion of a loom or textile machine in which the warp threadsare situated in a vertical plane, the harness frames or heddles arehorizontal, and which is designed to weave a number of similar fabricsin parallel vertical planes.

Referring to the drawings which form a part of this specification:-Figure 1 is an end elevation of a loom constructed and arrangedaccording to my invention, illustrating only such parts thereof as arenecessary, for the explanation of the said invention. Fig. 2 is anenlarged vertical section on line a-a of Fig. 1. Fig. 3 is alongitudil'lal section on line bb of Fig. 2.

In carrying out my invention I provide or form each shuttle c with arack d on the underside thereof to engage a pinion e keyed on a shaft frunning the whole length of the machine; there are two of these shafts7, 7, one on each side of the reed frame 9, the positions of said shaftsf, 7 being so arranged that the racks d on the underside of the shuttlesc are in engagement with the pinions c on the shaft on one side of thereed space before they leave the pinions on the shaft on the other side;the shuttles slide upon guides or the like .9.

Both of the shafts 7, f preferably pass through one end frame 72, of themachine and on each of them at this outer end is further keyed anotherpinion j. Both of these pinions engage a quadrant 70 also mounted onSpecification of Letters Patent.

the end frame it of the machine. This quadrant is coupled up by means ofa connecting rod Z to a short crank m, the latter being keyed on to atoothed wheel 41, having two short blanks or dwells 0 of concave form onopposite sides thereof. This wheel gears with another wheel 79 fast onthe driving shaft 9 of the machine and has two longer blanks or dwells rthereo The dwells on the two toothed wheels last mentioned ('11. and prespectively) are so arranged and timed that while they are in e11-gagement they give the necessary dwell or rest to the shuttles on eitherside to allow for the rise and fall of the reed: the toothed portions ofsaid wheels projecting beyond the face of the dwells or rests thereon engage as the driving shaft revolves and in combination with the quadrant7c, pinions j, shafts 7, f pinions e and racks (Z give the requisitethrow to the shuttles.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent isz- In a vertical loom, the combination ofreciprocating upright shuttles, placed side by side, racks on the bottomof the shuttles, pinions engaging with said racks, horizontal shaftscarrying said pinions, pinions on the ends of said shafts, a toothedquadrant engaging with the last named pinions, a pinion having dwellsthereon, means for connecting said pinion with the quadrant, and a gearwheel having dwells thereon engaging with the last named pinion saidgear wheel being connected with the driving means.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ROBERT ABELL.
